v0.6.2

Fixed

• install no longer adds a duplicate plugin entry when opencode-gemiterm-skills is already present under a different form (e.g. opencode-gemiterm-skills@latest or different casing). Added a shared normalizePluginName/isOurPluginEntry helper that strips version tags (@latest, @1.2.3) and lowercases before matching, used by addPluginToConfig, removePluginFromConfig, and isPluginInConfig. Scoped packages (@scope/pkg) are handled correctly so the leading @ isn't mistaken for a version separator.

Added

• Exported normalizePluginName and isOurPluginEntry from src/installer.ts for direct unit testing.
• 6 new tests in tests/skills.test.ts covering version-spec stripping, case-insensitivity, whitespace trimming, scoped-package handling, and matching/rejecting the right entries.
